Patent ID: 7136582

Claim:
A lighting unit fixed to an object to have the lighting unit installed therein for lighting up a vicinity of a predetermined focal point, the lighting unit comprising: a light emitting diode case having an accommodation space vertically formed and adapted to accommodate the object to have the lighting unit installed therein, and a lower end surface to which a plurality of light emitting diodes able to apply light to the predetermined focal point are fixed; a temperature control element having an accommodation space vertically formed and adapted to accommodate the object to have the lighting unit installed therein, and a lower end surface adapted to be brought into tight contact with an upper end surface of the light emitting diode case; and a heat radiating member having an accommodation space vertically formed and adapted to accommodate the object to have the lighting unit installed therein, a lower end surface adapted to be brought into tight contact with an upper end surface of the temperature control element, and an upper end surface having a heat radiating construction formed therein, the light emitting diode case, the temperature control element, and the heat radiating member being independent of one another, the lighting unit further comprising: a fixing member for being urged to at least one of the light emitting diode case and the heat radiating member by an elastic portion, and for contacting the other of the light emitting diode case and the heat radiating member to urge the other in a direction of the one to bring the light emitting diode case, the temperature control element, and the heat radiating member into tight contact with one another when the light emitting diode case, the temperature control element, and the heat radiating member are assembled integrally with one another.
